At SSD we make custom mesh roll-up doors designed specifically to keep pigeons and birds out, salt dry and workers safe.

​Bird and Pigeon droppings cause a potentially fatal disease called Histoplasmosis. It’s an infection caused by breathing in spores of fungus from their droppings. People usually get it from breathing in these spores when they’re airborne. Often found near open buildings and construction sites.

​Our design came to fruition after years in the industry. Speaking with engineers and DOT workers we’d hear about the constant issue of door tracks being knocked down and ripped out by loaders. With our roll-up door system there is no longer an issue or concern as our units are completely out of the way.

Our doors are meant to be open all winter season and closed when winter season is over.
